Selecting a Preferred Payment Instrument

ABSTRACT

Selecting payment instruments for proxy card transactions comprises associating a plurality of financial accounts with a user proxy account; establishing a model for the user account based on configuration data received from a user, the model comprising identification of a particular financial account to use as a backing instrument for a transaction; receiving data associated with a pending transaction regarding the pending transaction; identifying a financial account to use as a backing instrument for the pending transaction based on a comparison of the model with the pending transaction data; receiving a selection of an alternate financial account to use instead of the identified financial account as the backing instrument; modifying the model account based on the selection of the alternate financial account and the data associated with the pending transaction; and utilizing the modified model in a subsequent selection of a financial account for a subsequent transaction.

TECHNICAL FIELD

The present disclosure relates generally to proxy card payment transactions, and more particularly to selecting a preferred payment instrument in a proxy card payment transaction.

BACKGROUND

Payments can be conducted by a mobile device of a user with a point of sale terminal of a merchant. The mobile device can communicate with the terminal via near field communication (“NFC”), BLUETOOTH, barcode, Wi-Fi, infrared, or any other suitable communication technology. The mobile device can host a payment application, such as a digital wallet application module, that can complete a transaction with the terminal.

The point of sale terminal can obtain the payment information from the mobile device and transmit transaction details to the mobile device. The point of sale terminal can submit the transaction details to the card network to receive payment from the card issuer. A digital wallet application module on the mobile device can support multiple financial accounts and the cards associated with the account. The user can conduct a transaction with different financial instruments, such as credit cards, debit cards, stored value cards, or other payment cards, supported by the application.

Currently, when the user employs a proxy card to conduct the transaction, the user must select a backing payment instrument at the time of purchase with which to conduct the transaction. That is, at the time of purchase, the user must select a backing payment instrument and apply it to the purchase. Alternatively, the user may assign a payment instrument for all transactions until the assignment is changed or provide rules allowing a payment processing system to make the selection. Some payment instruments may be better suited for a particular transaction than other cards. For example, some payment instruments provide better rewards or provide better terms for transactions with certain merchant categories.

Conventional proxy card systems do not utilize user selections of payment instruments and other related transaction details to predict the preferred payment instrument and provide the predicted payment instrument to the user.

SUMMARY

One aspect of the example embodiments described herein provides a computer-implemented method to select payment instruments for proxy card transactions is described. The method comprises associating, using one or more computer devices, a plurality of financial accounts with a user proxy account, the user proxy account being maintained by the one or more computing devices; establishing a model for the user account based on configuration data received from a user associated with the user proxy card account, the model comprising identification of a particular financial account to use as a backing instrument for a transaction using the user proxy account; receiving data associated with a pending transaction with a merchant, the transaction being conducted between a merchant computing device and the user, the data comprising information regarding the pending transaction and information provided to the merchant computing device to identify the user proxy account; identifying a financial account from among the plurality of financial accounts to use as a backing instrument for the pending transaction based at least in part on a comparison of the model with the pending transaction data; receiving an input of a selection of an alternate financial account to use instead of the identified financial account as the backing instrument for the pending transaction; logging the data associated with the pending transaction and the selected, alternate financial account selected; modifying the model for the user account based on the selection of the alternate financial account and the data associated with the pending transaction; and utilizing the modified model for the user account in a subsequent selection of a financial account for a backing instrument for a subsequent transaction involving the user proxy account.

DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS Overview

In one example embodiment, payment processing systems enable users to utilize a single card to access multiple financial accounts maintained by multiple issuers. The user receives a proxy card from the payment processing system and either creates a new proxy card account with the payment processing system or associates the proxy card with the user's digital wallet account already maintained by the payment processing system.

The user then associates one or more financial card accounts with the proxy account. For example, the user can associate with the user's proxy card account multiple debit/credit cards maintained by multiple issuers (including the payment processing system operating as an issuer), stored value cards (for example, gift cards, prepaid cards, re-loadable transaction cards, exchange cards, and other forms of non-credit based value cards), loyalty cards or other store rewards cards, value added service accounts (for example, coupons, vouchers for prepaid offers, redemption offers, and other forms of offers), peer-to-peer transaction accounts, bank accounts and/or other forms of financial accounts.

The proxy card can be represented on a digital wallet application module or other payment application on a user computing device, such as a mobile phone. For example, the user proxy card account information, such as a proxy card account identifier, can be stored on the user computing device for use in a payment transaction by the digital wallet application module or other application. The user can communicate the proxy card account identifier and other transaction data to a merchant point of sale (“POS”) terminal using the user computing device via near field communication (“NFC”), barcode, BLUETOOTH, Wi-Fi communication, infrared, or other suitable communication technology. Alternatively, the proxy card can be represented as a physical payment card comprising a magnetic stripe or other machine-readable portion comprising the user's proxy card account identifier and other payment information. In this case, the user scans or swipes the proxy card at the merchant POS terminal to communicate the proxy card account identifier and other transaction data to the merchant POS terminal. Additionally or alternatively, the proxy card can be represented as any other suitable payment instrument, such as an RFID device or a smartcard. Additionally or alternatively, the payment instrument can be a digital wallet application module or other payment instrument on a user computing device for conducting online transactions, such as a mobile or desktop computer, laptop computer, or a television with one or more processors embedded therein and/or coupled thereto.

The merchant system creates a payment request for the transaction using the proxy card information and forwards the payment request to an acquirer, which forwards the payment request to a card network. The card network forwards the payment request to the payment processing system, which functions as the issuer for the payment request.

The payment processing system reads proxy card account information from the payment request and accesses the user's account associated with the proxy card. If the payment processing system is the issuer of the particular financial account selected as the backing instrument for the proxy card transaction, the payment processing system will approve or decline the transaction.

If another issuer maintains the particular financial account to be used as the backing instrument for the transaction, the payment processing system will generate and send a new payment request for the transaction to the other issuer via the card network (or via different card network). The payment processing system receives an authorization message from the other issuer via the card network if the transaction is approved.

The payment processing system forwards an authorization to the acquirer through the card network, which forwards the authorization to the merchant system. The authorization is based on the payment processing system's determination as the issuer to authorize the transaction or the authorization received from the other issuer.

The merchant system then approves the transaction, based on the authorization received from the payment processing system.

The user sets rules or preferences specifying which financial account will be accessed and used as the backing instrument when a proxy card transaction is attempted. The user can then add, delete, or change the default payment rules associated with the user's proxy card account. The user can change these default static rules, create new rules, or delete a rule. In an example embodiment, the user can access the proxy card account and modify the rules at any time, including a time immediately before a payment transaction is initiated. In an example embodiment, the user can access the proxy card account using a mobile device application, such as a digital wallet application module executing on the user's mobile computing device. The rules can be maintained on the digital wallet application module, on the user device, or on a server at the payment processing system. Throughout the specification, any of the functions described as being performed by the digital wallet application module or the user computing device can be performed by the payment processing system. Alternatively, any functions described as being performed by the payment processing system can be performed by the digital wallet application module or the user computing device.

When a user enters a merchant system location to conduct a proxy card transaction, the digital wallet application module on the user computing device can note the location of the user and other environmental factors, such as the time of day or the day of week. The digital wallet application module may access information regarding the environment of the user computing device continuously, when the digital wallet application module is opened on the user computing device, when the user indicates that a transaction is imminent, after a transaction is initiated, when the user computing device enters the location of a merchant system, or at any other suitable time.

The user computing device can determine the geo-location of the merchant system based on a location application on the user computing device. For example, the user computing device can use global positioning system capabilities of the user computing device or other location determining hardware or software to determine the geo-location of the merchant system. Alternatively, the user can manually identify the location by “checking in” to the location, such as on a social network site or in any suitable manner. A wireless connection between the user computing device and the merchant system point of sale system may alternatively provide location information to the user computing device.

The user selects a product for purchase. Throughout the specification, the term “product” can refer to any tangible or intangible product or service.

The user opens or otherwise initiates the digital wallet application module to conduct the transaction with the merchant system by presenting proxy card account information to the merchant system's POS terminal. The digital wallet application module displays a selected backing payment instrument to be used in the transaction with the merchant system when the user presents the proxy card of the user to the merchant system. The digital wallet application module can receive the card selection for the backing instrument from the payment processing system or the digital wallet application module may make the selection. The backing instrument may be selected based on any rules or preferences received from the user at the time of account configuration, at the time of associating payment instruments, or at any suitable time thereafter. In an example rule, the user may have input a preference that a department store utilize a card associated with the department store as the backing instrument whenever the user is at a location of the department store. In another example, a user may have input a preference to utilize a travel rewards card as the backing instrument whenever the user makes a travel related purchase.

If a user has not provided a rule or a preference that applies to a particular transaction, the payment processing system may recommend a backing instrument to the user based on the selections of other users. The payment processing system can access transaction histories of other users that have multiple backing instruments associated with the account of each user and determine the backing instrument selected for related transactions by each user. The payment processing system can rank the identities of backing instruments selected by other users of the payment processing system. The payment processing system can identify which of the backing instruments that is associated with the user is most often selected by other users. The payment processing system can recommend that the user select the identified backing instrument for use in the transaction with the merchant system.

In certain example embodiments, the user does not provide any initial rules or preferences to the payment processing system. The payment processing system or the user can select a default backing instrument and employ the default backing instrument for all transactions unless the user selects an alternative backing instrument.

The digital wallet application module can indicate to the user that a backing instrument selected by the digital wallet application module or the payment processing system will be utilized for a transaction that may be forthcoming while at the current location of the user. The indication can be a display of the backing instrument by the digital wallet application module on the user computing device when the user accesses the proxy card account on the digital wallet application module. Any suitable indication can be employed to alert the user to the selected backing instrument.

In certain example embodiments, the user is not provided with an indication of the backing instrument selected by the digital wallet application module for use in the transaction with the merchant system. The payment processing system can make the backing instrument selection and conduct the transaction with the selected backing instrument.

The user can conduct the transaction with the selected backing instrument or the user can indicate to the digital wallet application module that an alternate backing instrument is preferred. For example, the user can access a list of backing instruments on the user computing devise. The list of backing instruments can be presented on the digital wallet application module and the user can select a backing instrument that is different from the backing instrument selected by the payment processing system. Any other manner of choosing and selecting an alternate backing instrument can be employed by the user and the digital wallet application module. Then, the user can conduct the proxy card transaction with the merchant system using the alternate backing instrument as the backing instrument.

The digital wallet application module can log the circumstances of the transaction and the alternate backing instrument selected by the user. The circumstances can be stored in the user account on the digital wallet application module and/or the payment processing system. The circumstances can include any information associated with the transaction, such as the location of the merchant system, the identity of the merchant system, the category of the merchant system, the time of day, the day of the week, the season of the year, the environmental conditions, or an other suitable information.

The stored information can be included in a model of user preferences to be utilized in future card selections and recommendations. As the model gathers more useful information regarding the selections and preferences of the user, the payment processing system can make better backing instrument selections for the user. For example, the model may determine that while the user indicated a preference to use a particular credit card associated with an employer as the backing instrument, the user may prefer to use a personal credit card on the weekend. In another example, the model may determine that while the user indicated a preference to use a travel rewards credit card as the backing instrument for most restaurant purchases, the user prefers a personal debit card at coffee shops. In another example, the model may determine that the user prefers to use a business credit card as the backing instrument for all expenses when traveling to a particular city, such as the location of the corporate office of the user's employer. Any other suitable determinations may be predicted by the model based on the information logged with user transactions.

The model can determine from the user actions that a rule should be ignored or modified in certain circumstances. The payment processing system can use the model for selecting a backing instrument during future transactions. In an example, a user may have established a rule that selects a particular backing instrument for all airline flights. However, in the previous two transactions with a particular airline, the user has changed the backing instrument to an alternate backing instrument. The model can recognize a subsequent pending transaction with the particular airline, and the payment processing system can select the alternate backing instrument instead of the backing instrument the rule would have required.

Alternatively, the payment processing system can direct the digital wallet application module to provide the alternate backing instrument as an option to the user. For example, the digital wallet application module can indicate which backing instrument would be selected by the rules, but offer the user an optional backing instrument based on history of the user with the particular airline.

In an alternate embodiment, the features of the invention can be utilized in a transaction with the merchant system that is initiated by using a magnetic stripe card, RFID, smartcard, or any other physical payment instrument. The merchant system can initiate the transaction after receiving the user account information from the magnetic stripe card. The payment processing system or the merchant system can transmit a request to the user computing device to enter a backing instrument or a notice of the pre-selected backing instrument. The user can acknowledge the selection, make a new selection, or take no action.

In an alternate embodiment, all of the processes can be performed in an online transaction. The user computing device may attempt a transaction with an online merchant system. The merchant system can submit the transaction and the merchant system details. The payment processing system can determine the conditions of the transaction, such as the identity of the merchant system, the category of the merchant system, the time of day, the day of the week, the season of the year, or other suitable information. The backing instrument selection and any alternate backing instrument selection by the user can be performed in a similar manner to the example embodiments described herein.

The functionality of the example embodiments will be explained in more detail in the following description, read in conjunction with the figures illustrating the program flow.

The proxy card or other payment instrument can be represented as a magnetic strip card 120. The magnetic stripe card 120 can be a physical payment card comprising a magnetic stripe or other machine-readable portion comprising the user's proxy card account identifier and other payment information. In this case, the user scans or swipes the magnetic stripe card 120 at the merchant POS terminal 134 to communicate the proxy card account identifier and other transaction data to the POS terminal 134. Additionally or alternatively, the magnetic stripe card 120 can be represented as any other suitable payment instrument, such as an RFID device or a smartcard.

The payment processing system 140 includes a data storage unit 147 accessible by the web server 144. The example data storage unit 147 can include one or more tangible computer-readable storage devices. The payment processing system 140 is operable to conduct wireless payments between a user 101 and a merchant system 130. The payment processing system 140 is further operable to maintain a database to store transactions of the merchant system 130 and the user 101, recommend automatic payment recipients, and other suitable functions.

The user 101 can use a web server 144 on the payment processing system 140 to view, register, download, upload, or otherwise access the payment processing system 140 via a website (not illustrated) and a communication network 105). The user 101 associates one or more registered financial card accounts, including bank account debit cards, credit cards, gift cards, loyalty cards, coupons, offers, prepaid offers, store rewards cards, or other type of financial account that can be used to make a purchase or redeem value-added services with a payment account of the user 101. The card issuer 170 may be the issuer of the financial account being registered. For example, the card issuer, may be a credit card issuer, a debit card issuer, a stored value issuer, a financial institution providing an account, or any other provider of a financial account. The payment processing system 140 also may function as the issuer for the associated financial account. The user's 101 registration information is saved in the payment processing system's 140 data storage unit 147 and is accessible the by web server 144.

The user 101 also may use the web server 144 to define payment rules. The creation of a backing instrument model for a user is discussed in more detail hereinafter with reference to the methods described in FIG. 2.

The merchant system 130 may use a web server 135 to view, download, upload, create offers, sell products online, or otherwise access the payment processing system 140 via a website 136 and a communication network 105. The merchant system 130 represents an entity that offers products for the user 101 to purchase or use. The merchant system 130 includes a POS terminal 134. The POS terminal 134 may be operated by a salesperson that enters the purchase data into the POS terminal 134 to complete the purchase transaction. The merchant system 130 may be a physical location or an online merchant.

The user 101 may request a purchase from the merchant system 130. In an example embodiment, the purchase is initiated by a wireless “tap” of the mobile device 110 with the POS terminal 134. In an alternative example embodiment, the purchase is initiated when the user 101 enters an account identification number at the POS terminal 134 or in the mobile device 110. In another alternative example embodiment, the purchase is initiated online with the merchant server 135. The purchase may be initiated via the merchant website (not pictured). In yet another alternative example embodiment, the purchase is initiated by use of a permanent/temporary virtual/physical token, QR code, bar code, or other suitable machine-readable medium captured by the POS terminal 134. The merchant's POS terminal 134 interacts with an acquirer, the card network, the payment processing system 140, and the issuer.

Example Processes

The example methods illustrated in FIG. 2 are described hereinafter with respect to the components of the example operating environment 100. The example methods of FIG. 2 may also be performed with other systems and in other environments.

FIG. 2 is a block flow diagram depicting a method 200 for selecting a preferred card in a proxy card payment transaction, in accordance with certain example embodiments.

With reference to FIGS. 1 and 2, in block 205, the payment processing system 140 issues a proxy card account to the user 101. In an example embodiment, the user 101 requests a proxy card using a web server 144, and the proxy card is mailed to the user 101. The user 101 may be issued an account number to be used for transactions via the Internet before or after a physical card is received. In an alternative example embodiment, the payment processing system 140 mails an inactivated proxy card to the user 101. The proxy card is then activated by the user 101 before use. In an alternative example embodiment, a physical proxy card is not issued. The proxy card account information can be stored in the user device 110 and is used to make a payment via a NFC, Bluetooth, barcode, Wi-Fi, or other form of wireless tap of the user device 110 with the point of sale (“POS”) terminal 134. In an alternative example embodiment, the purchase is initiated when the user 101 enters an account identification number at the POS terminal 134 or in the user device 110. The account identification number may be the proxy card account number or a different number that links the payment transaction to the proxy card account. In yet another alternative example embodiment, a purchase is initiated by use of a permanent/temporary virtual/physical token QR code, bar code, or other suitable machine-readable medium that is read by the POS terminal 134. In these cases, the POS terminal 134 may comprise a scanner, camera, or other reading device that captures the proxy account information, such as a bar code or QR reader or other suitable reading device. The proxy account information may be printed in paper or other form.

The user 101 creates a new payment processing system 140 account or links the proxy card to an existing account on the payment processing system 140. The payment processing system 140 also may create or update an account on a proxy card application 115 on the user device 110 or on a digital wallet application module 111 on the user device 110. The digital wallet application module 111 may have proxy card application 115 operating on the digital wallet application module 111, or the proxy card application 115 may operate independently of the digital wallet application module 111. All functions throughout the specification described as being performed by the digital wallet application module 111 may be performed by the proxy card application 115.

In block 210, the user 101 activates the proxy card and associates one or more financial instrument accounts (for example, debit cards, credit cards, gift cards/stored value cards, loyalty cards/reward cards, peer-to-peer payment accounts, coupons, prepaid or other offers, and other accounts used to make a purchase or redeem value added services) with the proxy card account. In an example embodiment, the user 101 associates multiple financial instrument accounts with the proxy card account. The user 101 may perform this block by inputting identifying information for each financial payment instrument account. The user 101 may input the identifying information for each financial payment instrument account into the digital wallet account module 111, into a user interface of the payment processing system server 144, or any other suitable user interface.

In an example embodiment, one or more financial instrument account(s) are maintained by the payment processing system 140 and other payment instrument systems. In an alternative example embodiment, the payment processing system 140 maintains one or more of the financial instrument accounts and acts as the issuer for that financial instrument account. In another example embodiment, the financial instrument accounts are maintained by more than one payment instrument systems, including the payment processing system 140. Additionally or alternatively, one or more of the financial instrument accounts are issued by the card issuer 170.

In block 215, the user 101 establishes rules for selecting a payment instrument in a transaction. The user 101 sets rules or preferences specifying which financial account will be accessed and used as the backing instrument when a proxy card transaction is attempted. The user 101 can then add, delete, or change the default payment rules associated with the user's proxy card account. The user 101 can change these default static rules, create new rules, or delete a rule.

In an example embodiment, the user 101 can access the proxy card account and modify the rules at any time, including a time immediately before a payment transaction is initiated. In an example embodiment, the user 101 can access the proxy card account using a mobile device application, such as a digital wallet application module 111 executing on the user's mobile computing device 110. The rules can be maintained on the digital wallet application module 111, on the user device 110, or on a server at the payment processing system 140.

Any of the functions described as being performed by the digital wallet application module 111 or the user computing device 110 can be performed by the payment processing system 140. Alternatively, any functions described as being performed by the payment processing system 140 can be performed by the digital wallet application module 111 or the user computing device 110.

In block 220, a user 101 enters a merchant system 130 location to conduct a transaction. The merchant system 130 can be a store, restaurant, amusement park, gas station, airline, hotel, vendor, contractor or any suitable merchant system 130 that offers products for sale. The term “product” represents any tangible or intangible products, as well as services.

When a user 101 enters a merchant location to conduct a proxy card transaction, the digital wallet application module 111 on the user computing device 110 can note the location of the user 101 and other environmental factors, such as the time of day or the day of week. The digital wallet application module 111 may access information regarding the environment of the user computing device 110 continuously, when the digital wallet application module 111 is opened on the user computing device 110, when the user 101 indicates that a transaction is imminent, after a transaction is initiated, when the user computing device 110 enters the location of a merchant system 130, or at any other suitable time.

The user computing device 110 can determine the geo-location of the merchant system 130 based on a location application on the user computing device 110. For example, the user computing device 110 can use global positioning system capabilities of the user computing device 110 or other location determining hardware or software to determine the geo-location of the merchant system 130. Alternatively, the user 101 can manually identify the location by “checking in” to the location, such as on a social network site or in any suitable manner. A wireless connection between the user computing device 110 and the merchant system 130 point of sale (“POS”) terminal 134 may alternatively provide location information to the user computing device 110.

In block 225, the payment processing system 140 selects a payment instrument for use a transaction with the merchant system 130. The user 101 opens or otherwise initiates the digital wallet application module 111 to conduct the transaction with the merchant system 130 by presenting proxy card account information to the merchant's POS terminal 134. The digital wallet application module 111 displays a selected backing payment instrument to be used in the transaction with the merchant system 130 when the user 101 presents the proxy card of the user 101 to the merchant system 130. The digital wallet application module 111 can receive the card selection for the backing instrument from the payment processing system 140 or the digital wallet application module 111 may make the selection. The backing instrument may be selected based on any rules or preferences received from the user 101 at the time of account configuration, at the time of associating payment instruments, or at any suitable time thereafter.

In an example rule, the user 101 may input a preference that a department store utilize a card associated with the department store as the backing instrument whenever the user 101 is at a location of the department store. In another example, a user 101 may input a preference to utilize a travel rewards card as the backing instrument whenever the user 101 makes a travel related purchase. In another example, the user 101 may input a preference to use a card associated with a fuel provider for all purchases at gas stations. In another example, the user 101 may input a preference to use a particular card for any transaction being conducted in a foreign currency. Any other suitable rule can be established by the user 101 and utilized by the payment processing system 140 and the digital wallet application module 111.

If a user 101 has not provided a rule or a preference that applies to a particular transaction, the payment processing system 140 may recommend a backing instrument to the user 101 based on the selections of other users. The payment processing system 140 can access transaction histories of other users that have multiple backing instruments associated with the account of each user and determine the backing instrument selected for related transactions by each user. The payment processing system 140 can rank the identities of backing instruments selected by other users of the payment processing system 140. The payment processing system 140 can identify which of the backing instruments that is associated with the user is most often selected by other users. The payment processing system 140 can recommend that the user 101 select the identified backing instrument for use in the transaction with the merchant system 130.

In certain example embodiments, the user 101 does not provide any initial rules or preferences to the payment processing system 140. The payment processing system 140 or the user 101 can select a default backing instrument and employ the default backing instrument for all transactions unless the user 101 selects an alternative backing instrument.

The digital wallet application module 111 can indicate to the user 101 that a backing instrument selected by the digital wallet application module 111 or the payment processing system 140 will be utilized for a transaction that may be forthcoming while at the current location of the user 101. The indication can be a display of the backing instrument by the digital wallet application module 111 on the user computing device 110 when the user accesses the proxy card account on the digital wallet application module 111. Any suitable indication can be employed to alert the user 101 to the selected backing instrument.

In certain example embodiments, the user 101 is not provided with an indication of the backing instrument selected by the digital wallet application module 111 for use in the transaction with the merchant system 130. The payment processing system 140 can make the backing instrument selection and conduct the transaction with the selected backing instrument.

In block 230, the payment processing system 140 receives a selection of an alternative payment instrument to use in the transaction with the merchant system 130 from the user 101. The selection of an alternative payment instrument is optional for the user 101. The user 101 may decide to use the payment instrument that is recommended or is the default payment instrument. In the example, the user 101 can conduct the transaction with the selected backing instrument or the user 101 can indicate to the digital wallet application module 111 that an alternate backing instrument is preferred. For example, the user 101 can access a list of backing instruments on the user computing devise 110. The list of backing instruments can be presented on the digital wallet application module 111 and the user 101 can select a backing instrument that is different from the backing instrument selected by the payment processing system 140. Any other manner of choosing and selecting an alternate backing instrument can be employed by the user 101 and the digital wallet application module 111.

In an alternate example, the digital wallet application module 111 can make a request to the user 101 to provide a selection of a backing instrument after the transaction is initiated with the merchant system 130. For example, the user 101 can tap the user device 110 against a POS terminal 134 or the user 101 can swipe a magnetic stripe at a POS terminal 134. Then, the digital wallet application module 111 can ask the user 101 to make a selection of a backing instrument after the transaction is initiated. The digital wallet application module 111 can display a message to the user 101 to select the backing instrument. Alternatively, the POS terminal 134 can display the message to the user 101 to select a backing instrument. The user 101 can select the backing instrument on the user device 110, the POS terminal 134, or another suitable location. For example, the user 101 can select a backing instrument from a list on the digital wallet application module 111.

The user 101 can input the backing instrument selection into the digital wallet application module 111, into a user interface of the payment processing system server 144, or any other suitable user interface. The payment processing system 140 can receive the selection and stored the selection in a database, on the on the data storage unit 147, or any suitable data storage location. The backing instrument selection may be stored in a location that the payment processing system 140 can access for use in producing or modifying the model of the user 101 and for use in making future backing instrument selections and recommendations.

In block 235, the user 101 can conduct the proxy card transaction with the merchant system 130 using the alternate backing instrument as the backing instrument. That is, the user device 110 can transmit the proxy card information to the POS terminal 134, and the merchant system 130 can conduct the transaction with the payment processing system 140. For example, the user 101 can transmit the proxy card information via an NFC, BLUETOOTH, barcode, Wi-FI, infrared or other wireless transmission technology to the POS terminal 134. Alternatively, the user can provide a magnetic stripe card to the POS terminal 134. Any suitable manner of providing the proxy card information to the merchant system 130 can be utilized.

The merchant system 130 can recognize that the proxy card is associated with the payment processing system 140 and can contact the payment processing system 140. The merchant system 130 can provide the transaction request and transaction details to the payment processing system 140 and the transaction can be conducted. The payment processing system 140 can create a second transaction request with the issuer of the selected backing instrument and conduct a second transaction with the issuer of the selected backing instrument. After receiving an authorization for the transaction from the issuer of the selected backing instrument, the payment processing system 140 can provide an authorization for the transaction request from the merchant system 130. In an alternate example, the merchant system 130 can provide the transaction request to a card network and the card network can recognize that the payment processing system 140 is the issuer of the proxy card. Any other participant of the transaction can recognize the proxy card and direct the transaction request to the payment processing system 140.

In block 240, the payment processing system 140 incorporates the circumstances of the transaction into a card selection model of the user 101. The digital wallet application module 111 can log the circumstances of the transaction and the alternate backing instrument selected by the user 101. The circumstances can be stored in the user account on the digital wallet application module 111 and/or the payment processing system 140. The circumstances can include any information associated with the transaction, such as the location of the merchant system 130, the identity of the merchant system 130, the category of the merchant system 130, the time of day, the day of the week, the season of the year, the environmental conditions, or an other suitable information.

In block 245, the payment processing system 140 utilizes the card selection model in future transactions. The stored information can be included in a model of user preferences to be utilized in future card selections and recommendations. As the model gathers more useful information regarding the selections and preferences of the user 101, the payment processing system 140 can make better backing instrument selections for the user 101. For example, the model may determine that while the user 101 indicated a preference to use a particular credit card associated with an employer as the backing instrument, the user 101 may prefer to use a personal credit card on the weekend. In another example, the model may determine that while the user 101 indicated a preference to use a travel rewards credit card as the backing instrument for most restaurant purchases, the user 101 prefers a personal debit card at coffee shops. In another example, the model may determine that the user 101 prefers to use a business credit card as the backing instrument for all expenses when traveling to a particular city, such as the location of the corporate office of the employer of the user 101. Any other suitable determinations may be predicted by the model based on the information logged with transactions of the user 101.

The model can determine from the actions of the user 101 that a rule should be ignored or modified in certain circumstances. The payment processing system 140 can use the model for selecting a backing instrument during future transactions. In an example, a user 101 may have established a rule that selects a particular backing instrument for all airline flights. However, in the previous two transactions with a particular airline, the user 101 has changed the backing instrument to an alternate backing instrument. The model can recognize a subsequent pending transaction with the particular airline, and the payment processing system 140 can select the alternate backing instrument instead of the backing instrument the rule would have required.

Alternatively, the payment processing system 140 can direct the digital wallet application module 111 to provide the alternate backing instrument as an option to the user 101. For example, the digital wallet application module 111 can indicate which backing instrument would be selected by the rules, but offer the user 101 an optional backing instrument based on history of the user 101 with the particular airline.

In an alternate example, the payment processing system 140 can provide a recommendation to the user 101 to override the rules for a certain period of time based the situation of the user 101. The determination can be made based on a set of conditions recognized by the model. For example, the model may recognize that the circumstances of the user 101 indicate that a business trip is ongoing. The model may determine that user 101 is on a business trip based on the location of the user, the repeated use of a company credit card, the merchant systems 130 frequented, or any other circumstance received by the model. The digital wallet application module 111 can display an option to the user 101 to override the rules and employ a company credit card or a set of cards with until the user 101 returns to the city of residence of the user 101 or until the user 101 cancels the overriding of the rules. The user 101 can select the option to change to the company credit card and enter the selection into the digital wallet application module 111. In another example, the payment processing system 140 can recognize that the user 101 is in a location that indicates that the user 101 is on a vacation. The digital wallet application module 111 can display an option to the user 101 to override the rules and employ a travel rewards credit card until the user returns to the city of residence of the user 101 or until the user 101 cancels the overriding of the rules. Any other set of user circumstances can be recognized by the payment processing system 140 that cause the to digital wallet application module 111 to provide the user 101 with a request to suspend or alter the rules.

In an alternate embodiment, the payment processing system 140 can allow the user 101 to maintain more than one model. That is, the user 101 may have a model for weekends, a different model for weekdays, a different model for vacations, or a model for any other aspect of the user's 101 activities. The user 101 or the payment processing system 140 can establish different rules for the different models, and the payment processing system 140 can modify the rules for the different models as described herein. In an example embodiment, the models can be determined based on a set of conditions recognized by the model. The payment processing system 140 can recognize that a different model would be more appropriate based on the activities of the user 101, and recommend to the user 101 to switch the model being utilized.

In an example, the payment processing system 140 may recognize that the circumstances of the user 101 indicate that a business trip is ongoing. The model may determine that user 101 is on a business trip based on the location of the user, the repeated use of a company credit card, the merchant systems 130 frequented, or any other circumstance received by the model. The digital wallet application module 111 can display an option to the user 101 to switch to a business travel model of the user 101. The user 101 can select the option to change to the business travel model and enter the selection into the digital wallet application module 111. In another example, the payment processing system 140 can recognize that the user 101 is in a location that indicates that the user 101 is on a vacation. The payment processing system 140 can automatically switch to the corresponding model for the user. Alternatively, the digital wallet application module 111 can display an option to the user 101 to switch to a vacation model of the user 101 until the user returns to the city of residence of the user 101 or until the user 101 cancels the overriding of the rules. Any other set of user circumstances can be recognized by the payment processing system 140 that cause the to digital wallet application module 111 to provide the user 101 with a request to suspend or alter the rules.

In another example, the user 101 selects a different model by making a selection of the model to be utilized before the user 101 begins a business trip, vacation, weekend, or any other activity or time frame that would require a different model. In another example, the model to be used can be scheduled based on a calendar or other time based program. For example, the user 101 can configure the payment processing system 140 to use a business model during working hours and switch to a personal model after hours and on the weekends.

In an alternate embodiment, all of the processes can be performed in an online transaction. The user computing device may attempt a transaction with an online merchant system 130. The merchant system 130 can submit the transaction and the merchant details. The payment processing system 140 can determine the conditions of the transaction, such as the identity of the merchant system 130, the category of the merchant system 130, the time of day, the day of the week, the season of the year, or other suitable information. The backing instrument selection and any alternate backing instrument selection by the user 101 can be performed in a similar manner to the example embodiments described herein.
